Repair
Process

New England Door Closer is an authorized
factory repair center for companies like LCN, Yale, Norton,
Corbin, Russwin and Sargent for over 50 years. While we repair
most current vintage closers, obsolete units, particularly
traditional or potbelly units are
our specialty. Many of the units we repair are over 75 years
old.

After each unit is received and catalogued,
it is disassembled using factory specific tools. Upon completion
of disassembly, each unit is cleaned and rinsed to make sure
it is free from the deposits of old oil, packings and the
various debris that accumulates over time.

Closers are then taken to our
assembly mechanics. Each individual internal part is visually
and mechanically inspected. Anything deemed to be worn beyond
acceptable tolerance is replaced with a new factory original
part. NEDC is able to do this even with obsolete closers as
agreements were made with various manufacturers to purchase
part inventories and machine molds as units were discontinued.
By doing this, NEDC is able to reproduce common internal parts
to original factory specifications.

Once the internal parts have been replaced,
NEDC rebuilds the unit and fills it with our own custom blend
of hydraulic oil designed specifically for the heavy duty
wear and tear closers are accustomed to. Each closer is then
re-packed with brand new packing (made to original factory
specifications) and tested thoroughly. The unit is left to
sit at room temperature for several hours to make sure packings
and gaskets seated properly during the assembly process.

After a second testing is completed, each
closer is sent to our paint shop where
a finish most closely resembling the original is applied.
Upon drying, the closer is sent to our traffic department
where it is carefully wrapped and shipped or delivered by
an NEDC sales and service representative.
